Oklahoma 2018 - 577.1 ypg, 8.91 ypp, 49.0 ppg.
LSU 2019 - 556.0 ypg, 7.64 ypp, 47.8 ppg.

Watching LSU this year, they remind me a slightly better version of 2018 OSU and a noticeably better version of 2018 Oklahoma (at least on defense, their offenses are similar). 2019 Clemson is slightly below 2018 Clemson. Despite their weak schedule, they are destroying everyone lately. 2019 Clemson is pretty good, let’s not fool ourselves. 2019 OSU is significantly better than 2018 OSU, particularly on defense, and the offense, while only slightly better statistically, is more balanced.
So for me, Clemson and Ohio State are the top two teams and are in a tier by themselves. LSU is #3 in their own tier. #4 begins a third tier with a bunch of really good but flawed teams in it. Georgia, Alabama, Oregon, Utah, Penn State, Wisconsin, Xichigan, Minnesota, Oklahoma, Baylor, etc. Throw in Florida if you like.
I think LSU will struggle against Clemson or OSU because both have elite defenses to slow down LSU, and elite offenses to expose LSU’s defensive shortcomings. It wouldn’t surprise me if Georgia beats them in the SEC title game, not because Georgia’s elite, but because LSU might not be.
